Interesting Facts
Volcanic terrain is the result of the accumulation of erupted lava, unlike mountains that are the result of erosion of earth’s crust, uplifting, folding, and faulting. A vent that connects the molten areas or molten rock(magma) are formed through a series of cracks beneath and within the volcano. Approximately there are 1,350 potentially active volcanos world wide. link
About the Plot
The bubbles are showing the total number of volcanos in those regions
The color scheme is showing the different types of volcanos
The popups show the name of the volcano and when it last erupted
Interesting Facts About Plot
There are about 954 volcanoes in the world.
These volcanoes are distributed across the globe with Asia having the highest number with 298 and Oceania having the lowest number with 84.
The Volcanic Explosivity Index (VEI) is a scale that describes the size of explosive volcanic eruptions based on magnitude and intensity ranging from 1 (lowest) to 6 (highest).
There are also different types of volcanoes as listed: Shield(s), Stratovolcano, Stratovolcano(es), Caldera, Submarine, Shield, Volcanic field, Fissure vent(s), Compound, Complex, Pyroclastic shield, Pyroclastic cone(s), Pyroclastic cone, Caldera(s), Lava dome(s), Lava cone, Crater rows, Maar(s), Tuff cone(s), Complex(es), Subglacial, Lava dome, Lava cone(s), Tuff cone, Lava cone(es), Stratovolcano?.
This plot shows major eruptions (VEI and year of eruption) from around the world since the 1700’s while showing the continental location and country of each volcano. The plot also shows the population within 100,000 km of the volcano telling you the number of people that may be affected if any of these volcanoes erupt and the volcano type.

Interesting Facts
Japan is located on the “Ring of Fire” which is a chain of volcanoes that stretches 40,000 kilometers. There are over 111 active volcanoes in Japan. The majority of mountains in Japan were formed as volcanoes.
About the Plot
Each triangle represents an eruption
The height of each triangle represents the volcanic explosion index
Each color represents the subregion the eruption occured in
